My research at RUB focuses on understanding spatial navigation and representation of space in medial temporal lobe of the brain via grid cells, place cells, spatial view cells, head direction cells. It is assumed that brain combines different types of inputs such as motor feedback, visual inputs etc to generate these spatial and orientation selective cells. I'm implementing mathematical framework which can extract location information from these inputs on ePuck robot. Finally, I would be comparing obtained results with that of experiments on animals.
I completed my M.Sc. degree in Physics at IISER-Kolkata (Indian Institute of Science Education and Research-Kolkata) in India. My thesis focused on probing and exploiting biological system using optics. There were two parts of the thesis; the first part was about quantifying physical properties of biological tissues from Muller matrix using different matrix decomposition methods. In the second part of the thesis I used fractal techniques (MFDFA) to extract structural parameter from light scattered by cancer cells. It allowed us to distinguish cancer cell at different stages.
